Kalmaegi, the 20th tropical cyclone to batter the Philippines this year, was moving northwestward at 25 kph (16 mph) and was forecast to start shifting away from the western section of the archipelago into the South China Sea later Tuesday.

An elderly villager drowned in floodwaters in Southern Leyte, where a provincewide power outage was also reported, officials said in an initial report without providing other details.

Ahead of the typhoon's landfall, disaster-response officials said more than 150,000 people had evacuated to safer ground in eastern Philippine provinces. Authorities warned of torrential rains, potentially destructive winds and storm surges of up to 3 meters (nearly 10 feet).

The typhoon, which has a broad wind band spanning about 600 kilometers (373 miles), was expected to batter central island provinces, including , which is still recovering from a 6.9-magnitude earthquake on Sept. 30 that left at least 79 people dead and displaced thousands when houses collapsed or were severely damaged.

On central Negros island, villagers were warned that heavy rains could cause volcanic mudflows on , which has been emitting plumes of ash and steam in recent months, according to the Philippine Institute of Volcanology and Seismology.

In Eastern Samar, one of east-central provinces first lashed by Kalmaegi, Gov. RV Evardone ordered mandatory evacuations and said residents readily moved to safety.

, one of the most powerful tropical cyclones on record, slammed ashore into Guiuan town in Eastern Samar in November 2013 then raked across the central Philippines, leaving more than 7,300 people dead or missing, flattening entire villages and sweeping scores of ships inland. Haiyan demolished about a million houses and displaced more than 4 million people in one of the country’s poorest regions.

“Nobody’s complaining among the residents because of their experience with Yolanda. They know it’s better to be safe than sorry,� Evardone told The Associated Press, referring to Haiyan’s Philippine name.

Interisland ferries and fishing boats were prohibited from venturing into increasingly rough seas, stranding more than 3,500 passengers and cargo truck drivers in nearly 100 seaports, the coast guard said. A number of domestic flights were canceled.

The Philippines is battered by about 20 typhoons and storms each year. It is often hit by earthquakes and has more than a dozen , making it one of the world’s most disaster-prone countries.
